Description
Technical Field
The utility model relates to an electrochromic technical field, concretely relates to electrochromic lens and AR glasses.
Background
The AR glasses based on the waveguide technology generally comprise a display module, a waveguide and a coupler. The light emitted by the display module enters the coupling device and is coupled into the optical waveguide, and the light is transmitted forwards in the waveguide in a total reflection mode, and is coupled out of the optical waveguide and then enters the human eye for imaging when reaching the coupling device. When a user moves from indoor to outdoor and moves from a weak background light environment to a strong background light environment, the light emitted by the AR glasses is too weak compared with the strong background light, and the user can hardly see clear images.
In order to solve this problem, there is an attempt to provide a color-changing lens on the far-eye side of the AR lens, which can adjust the transmittance and thus the luminous flux of the incident ambient light as required.
Prior art I (application No.: 201922262363.3) discloses the following structure: the two transparent substrates are placed in a staggered mode, the conducting layers are placed face to form a cavity, and electrochromic materials (namely EC materials) are placed in the cavity; the problems with this structure are as follows:
1. the structure is realized by forming a hollow cavity and then pouring the EC material into the cavity in a liquid pouring mode. The EC material used for infusion is an viologen-based EC material, generally in a liquid state, which forms a gel state upon curing. As the violet essence EC material contains the electrolyte of propylene carbonate and lithium salt, and the propylene carbonate is one of the plasticizers, the EC material cannot have good bonding performance, and the structure between two pieces of glass can only be realized by the sealing bonding glue at the edge. The structure is unstable, and the sealing adhesive is easy to lose effectiveness when falling and colliding, so that the hollow cavity structure leaks air, misplaces and even leaks liquid;
2. the filled EC material has no way to form the structure of electrochromic device/ion conductor layer/ion storage layer, and the ion conductor layer is used for conducting ion non-conducting ions, similar to the diaphragm of lithium battery. With this structure, the EC device has a memory effect and can maintain a color change state before power-off even when not powered on. Therefore, the structure in the first prior art has no memory effect, needs to be powered on all the time to maintain the color changing state, and needs to continuously consume power. This is very unfriendly to the use of portable consumer electronics such as AR glasses.
Prior art II (application No.: 202021991249.0) discloses the following structure: the first conducting layer and the first color changing layer are arranged on a first substrate layer, the second conducting layer and the second color changing layer are arranged on a second substrate layer, the first color changing layer and the second color changing layer are arranged face to face, and the middle of the first color changing layer and the second color changing layer are laminated by electrolyte. The electrolyte gel of this patent is actually an ion conducting layer, so the device has a memory effect. The problems with this structure are as follows: the electrolyte adhesive in the market is thick, and needs the banding technology, avoids the erosion of water oxygen in the air to the electrolyte adhesive.

Wherein the stress protection layer 001 is in particular a silicone layer, also referred to as OC0 layer, with a thickness in the range of 0.1 to 5.0 micrometers, preferably 0.5 to 1.5 micrometers. The OC0 layer may cover the subfissure of the glass surface and penetrate into the filling subfissure. The stress protection layer 001 has good bonding force after being cured, bonding can be formed at a hidden crack part, hidden crack expansion is prevented, and in addition, a buffer layer is formed due to the elasticity of the OC0 layer, so that the impact of film forming particles on the transparent substrate A101 can be effectively relieved in the film coating process; the strength of the glass is protected from being obviously reduced during physical deposition through the two principles.
Processing of the OC0 layer: before the transparent substrate A101 is coated, the glass is cleaned, and optionally, the dyne value of the glass is lifted by plasma bombardment. And then spraying the OC0 solution on the surface of the transparent substrate A101 by using ink-jet printing or spraying equipment, baking and curing to form OC0 on the surface of the transparent substrate A101, and then plating a subsequent film layer on the substrate frame.

The transparent protective layer 008 is used to prevent corrosion and damage of organic small molecules (such as plasticizer) in the optical adhesive to the inorganic EC composite functional layer 100. The transparent protection layer 008 can be made of silicon oxide, silicon nitride, silicon aluminum oxide, or the like, and is formed by evaporation or magnetron sputtering, and the thickness is 30-300 nm.
The stress protection layer 001, the color matching layer 002, the first transparent conductive layer 003, the inorganic EC composite functional layer 100, the second transparent conductive layer 007 and the transparent protection layer 008 are sequentially formed into a film on the transparent substrate A101 in a magnetron sputtering or evaporation mode, and are arranged on the near-to-eye side in the processing process of forming the lens.
The first optical adhesive 011 bonds the transparent substrate B102 with the transparent protective layer 008 (in the case where the transparent protective layer 008 is present) or with the second transparent conductive layer 007. The first optical adhesive 011 can adopt OCA or OCF, the thickness of which is 10-1000 micrometers, and the total thickness of the plating layers on the transparent substrate a 101, that is, the total thickness of the toning layer 002, the first transparent conductive layer 003, the inorganic EC composite functional layer 100, the second transparent conductive layer 007 and the transparent protective layer 008 is not more than 3000nm, so the actual structure is similar to that shown in fig. 4 and 5, fig. 4 shows the case that the stress protective layer 001 exists, and fig. 5 shows the case that the stress protective layer 001 does not exist. Fig. 4 and 5 do not show the AF layer and the AR layer.
As shown in fig. 4 and fig. 5, if edge deletion (laser or physical edge deletion) is performed on all the plating layers on the transparent substrate a 101 except the stress protection layer 001, so that the total plating layer is retracted relative to the transparent substrate a 101, and then the transparent substrate B102 is attached by the first optical adhesive 011, according to the industry experience, since the thickness of the first optical adhesive 011 is usually selected to be 20 to 100 micrometers, and the size is much larger than five times of the total plating thickness of 3 micrometers, the first optical adhesive 011 can cover all the plating layers on the transparent substrate a 101 and bubbles are not easily generated. In the process of attaching the first optical adhesive 011, the near-to-eye side of the first optical adhesive 011 forms the package space 200 naturally, and thus the package of the coating (the toning layer 002, the first transparent conductive layer 003, the inorganic EC composite functional layer 100, the second transparent conductive layer 007 and the transparent protective layer 008) on the transparent substrate a 101 including the inorganic EC composite functional layer 100 is completed.
The transparent substrate B102 may be a glass or resin lens, and in view of the fall-resistant property, a resin lens is preferable, the resin lens may prevent falling, and the transparent substrate B102 may have a shape corresponding to the transparent substrate a 101, and the two may be closely attached.

The second optical cement and the first optical cement are made of the same material.
The water oxygen barrier film 012 can be a commercially available water oxygen barrier film 012, such as 3M brand, duPont brand, kangde brand, etc. the water oxygen barrier film 012 should have a water vapor transmission rate of less than 10 -3 Grams/(square meter day) to enhance the protection of the entire electrochromic lens from moisture on the far-eye side, especially when the transparent substrate B102 is a resin rather than glass.
EXAMPLE III
As shown in fig. 11 and 12, an electrochromic lens includes, from outside to inside, a fingerprint-proof layer 302, an optical antireflection layer 301, a transparent substrate a 101, a stress protection layer 001, a first transparent conductive layer 003, an inorganic EC composite functional layer 100, a second transparent conductive layer 007, a color-adjusting layer 002, a transparent protection layer 008, a first optical adhesive 011, a water and oxygen barrier film 012, an optical antireflection layer 301, and a fingerprint-proof layer 302, which are sequentially disposed.
Namely, the difference between the third embodiment and the second embodiment is that: the original sequence of each film layer of the electrochromic lens is reversed; because the color modulation layer 002 is used for adjusting the reflected light of the electrochromic lens to human eyes, the color modulation layer 002 is adjusted to the near-to-eye side of the electrochromic composite layer, so that the color modulation layer 002 is positioned between the transparent protective layer 008 and the second transparent conductive layer 007; the second optical cement 013 and the transparent substrate B102 are eliminated; the package space 200 in the third embodiment is located on the far-eye side of the first optical cement 011.
